REMOVABLE-TYPE FOURDRINIER IPAIPER-MAKING MACHINE.

Application filed April 16, 1926. Serial No. 102,388.

This invention relates to a removable type Fourdrinier paper makingmachine and more particularly to a Fourdrinier wherein the couch andbreast rolls are removable with the table structure as a unit tofacilitate the changing of wires.

In my copending application, breast roll transfer mechanism forFourdrinier paper making machine, Serial No. 727,638,. filed July 23,1924, now Patent No. 1,599,402, issued Sept. 14, 1926, I have describedmeans for transferring the breast roll from a separate support to thetable structure for removal thereon during the changing of wires. I nowpropose to embody the principles of that invention in my presentconstruction and also to provide means for supporting the suction rolleither permanently or temporarily upon the table structure. By such acombination, the ease with which wires may be changed on the machine isgreatly increased.

It is, therefore, an object of this invention to provide a removabletype Fourdrmier paper'machine wherein the couch roll may be supported onand removed with the removable table structure.

It is a further object of this invention to provide a Fourdrinier havinga laterally re- -movable table and a suction couch roll normally mountedon said table and removable therewith as a unit.

It is a further object of this invention to provide a Fourdrinier havinga laterally removable table, breast and couch rolls sep arately mountedfrom said table and means for transferring said breast and couch rollstable for removal therewith.

it is a further object of this invention to ride a laterallyremovableFourdrinier of paper machine wherein the couch and breast rolls areadapted to be moved relatively towards or away from each other llheinvention a preferred form) is illustrated in the accompanying drawingsand hereinafter more fully described.

Un the drawings: Figure l is a side elevational' dlagrammatic view ofthe Fourd'rinier end of a paper machine, with parts broken, showing thepreferred form of my invention.

Figure 2 is a top plan view of the laterally removable table structureshown in Figure 1, showing theoperation in dotted mes.

Figure 3 is a fragmentary view of the couch roll and couch end of theFourdrinier frame showing amodified construction.

Figure 4 is a view similar to Figure 3 showing a second modified form ofconstruction.

, As shown on the drawings:

In Figures 1 and 2, the reference numeral 1 indicates one'of a pair of Ibeams-forming the side rails of a'laterally removable Fourdrinie'r tablestructure, and supporting the usual table or tube rolls 2 and suctionboxes 3. Said table structure, together with the tube rolls 2 andsuction boxes 3, is adapted to be laterally removed by rolling the sameout on rollers 6 over tracks 4, which may be swung out or otherwisemoved into the position shown in Figure 2, parallel to and forming acontinuation of tracks 5 on which the table structure normally rests.Said rollers 6 are supported is bearing brackets 7 from the table rails1 and are operated by means of a driving means 8 through the connectingshafting 9. The rails 5 are supported on pedestals 10, one end of eachof said rails 5 being provided with a pivot post 11 and the other endbeing adapted to be locked in normal transverse position by lockingmeans 12. The structure and operation of my removable Fourdrinier tableis slmilar to that described in the copending application to AlonzoAldrich and myself, removable type Fourdrinier paper making machine,Serial No. 57,272, filed September 19, 1925.

The breast end of the machine'coniprises a breast roll 13, havingjournals 14 removably mounted on a supporting pedestal 15. An apron 16,suitably mounted in front of said breast roll 13, conducts the stockonto a wire 17 running around said breast roll 13 and over the tuberolls 2 in the usual manner. Wire guide rolls 18 and stretch rolls 19are positioned substantially as shown.

llhe breast roll 13 is adapted when a Wire is to be changed, to beremoved from the pedestal 15 over onto supporting brackets or shelves 20forming a part of the rails, and provided with grooves 21 for receivingthe breast roll journal 14. This construction is above referred to.

described in my co-pending application It will be noted that in somoving the breast roll 13 the eflect is to shorten the effective lengthof the Fourdrinier and to produce the necessary slack in the wire forremoving the wire or for slippingpn anew wire, as will be understood byone skilled in the art of paper making.

At the couch end of the Fourdrinier frame, the'table rails are providedwith lower ofiset extensions 22 on which are mounted bearings 23, boltedor otherwise secured thereto. A suction couch roll 24 -is adaptedto bejournaled in said bearing 23 so as to be a part of the table structureand to be removable therewith as a unit. A sectional suction line 25having a removable section 26 is used in place of the usualsemi-permanent line to the suction couch roll to facilitate itsdismantling prior to moving out the table structure. Said section 26 isprovided with flanged ends 27 having circumferential slots adapted toreceive bolts 28 pivotally secured to adjacent flanged ends 29 of thesuction line 25. hen the section 26 is to be removed, the nuts 30o'n-said bolts 28 are loosened up and thebolts swung out of the slots.With this section 25 removed, it is then possible to move the tablestructure out from the rest of the machine. The operation is as follows:The modusoperandi when changing a wire on the machine is substantiallyas follows: First, the removable section 25 of the suction line is takenout and the tension on the wire is lessened by either adjusting or re.moving entirely the stretch rolls 19. It may also be necessary to removethe guide roll; 18, depending upon the set up ofthe machine. Then thebreast roll 13 is moved over from its pedestal 15 on to the tablestructure, the breast roll journals resting in the grooves 21 of thesupporting brackets 20. The moving of the breast roll may beaccomplished by a crane or by methods set forth in my application abovereferred to. The wire 17 being now slack may be supported away from the'table structure so that the latter may be moved out from the loopedwire.

The rails 4 are next moved into position if not already there, and thetable structure moved out laterally onto said rails by operation of themotor or other driving means 8.

The inner rails 5 are now swung along parallel to the side structuralbeams 31 and the old wire wound up and removed.

The new wire is then supported in the position occupied by the old wire,the tracks 5 swung back into normalposition and the table structure runback onto said tracks 5. The breast roll 13 is moved back onto thepedestal 15 and the wire rolls 18 and 19 'returned to their places. Thesection 26 of the suction line 25 is also slipped into place and boltedsecurely.

The remarkable simplicity of the above described operations and theimprovements represented by my present Fourdrinier construction overformer types of Fourdrinier construction will be obvious to one familiarin time and labor is efiected by such improvements.

In .Figure 3, I have shown a modified constrution of the couch "end'ofthe Fourdrinier. In place of the stationary couch rolls 24 shown inFigures 1 and 2, I provide a removable couch roll 32. supported from aseparate pedestal '33. Said. couch roll 32, which may or may not be ofthe'suctiontype, is journaled in cylindrical bearings 34, which areremovably mounted in arcua'te' shaped with paper making practice. Agreat saving supporting brackets 35, bolted or otherwise I secured tosaid pedestal 33. The circumference of said bearings 34 is provided withgear teeth 36, adapted to mesh'with teeth 37 formed on the base of saidbrackets 35. Lo'cking devices are provided to retain said hearings inplace comprising uprightslotted members 38 each forming a part. ofthebrackets 35, and lug 39 adjustably bolted to said members 34 by bolts41 and having teeth 40 adapted to be inserted between any two ad-.

jacent teeth 36. 'Set screws 42 are provided to lock the bearings 34 tothe journals of the roll 32when the'roll is to be transferred, -Asquared stub shaft 43 formed on each of the bearings 34 serves as meansfor applying a wrench or crank to .turn the roll.

When a wire is to be changed the bolts 41 are first loosened and thelocking pins 40 raised out of locking position. The set screws 42 arethen tightened to lock the-beanings 34 to the roll journals anda-wre'nch or crank is applied to the stub shaft 43. A bridge beam 44 isnext laid to span the gap between each of the pedestals 33 and the loweroffset extensions 45 of the Fourdrinier table rails 46. Said bridgebeams 44 and extensions 45 are each provided with rack teeth 47 to forma continuation'of-the teeth rate from the Fourdrinier table structureSaid table structure includes side rails 51'] having lower ofi'setlongitudinal extensions 52 provided with pockets 53 in which thejournals 54 of said roll 48 are adapted to rest when the wire is beingchanged.

In the operation of changing a"wire, the upper halves of the bearings 49are removed,

and the couch roll 48 is lifted up bodily by 'a crane or other liftingmeans and deposited on the extensions 52, where it rests during thelateral removal of the table,

Other ways of supporting the couch roll ried by the table structure forremoval therewith as a unit when the wire is to be changed. The breastroll should also be carried by the table structure during its lateralremoval, but that invention forms the subject ofmy c'opendingapplication above referred to.

It should be noted that in any of the forms of my invention described,there is effected a relative movement of the breast and couch rollstoward or away from each other during the wire changing operation.

I am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range without departing. fromthe principles of thisinvention, and I therefore do not purpose limitingthe patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. Ina removable type Fourdrinier paper machine, the combination with aremovable table, of a suction couch roll adapted to be supported thereonfor removal therewith.
